Few people know that the Ruc people were once one of the last isolated communities in Vietnam. Before 1959, they were almost completely separated from the outside world, living in the primeval forests of Phong Nha – Ke Bang National Park, maintaining a hunter-gatherer lifestyle that had existed for centuries. The Ruc resided in caves, rock shelters, or mountain bases near natural water veins flowing from limestone mountains. It is precisely these water sources—referred to by locals as "ruc" that became the origin of the ethnic group's name.

Their lives depended entirely on nature. Their main food consisted of wild yams, sago palm powder (doac), stream fish, rock snails, and small game hunted in the forest. They had not yet learned farming, had not established a settled lifestyle, and still preserved many primitive customs such as striking stones and iron to make fire, using fire for warmth, and keeping wild beasts and insects away. By late 1959, during a patrol, the Ca Xeng Border Guard discovered the Ruc community living in caves. After months of encouragement, the first 11 households with 34 individuals left the forest to settle in the Ruc Lan Valley. This was considered an important milestone, marking the beginning of an integration journey for a community that once faced the risk of extinction.
According to researchers, the Ruc are descendants of the pre-Viet-Muong population, belonging to the Viet-Muong language group. To this day, they are still considered one of the communities preserving many ancient cultural traces, contributing to the rich cultural tapestry of the Quang Binh region.
